Parsing web page to JSON

Question

I want to parse data from a web page and store it to a JSON file and use it when needed on ASP.NET webform web page. Please tell me how to do that?

 

For example take this URL: http://www.railyatri.in/time-table/19718-chandigarh-jaipur-intercity-cdg-to-jp

 

I want to parse name of station, time of arrival and time of departure in JSON file which I can later on use to display on my ASP.NET webform page.
